I lived in a flat with my DH a few years back. We were 1st floor and rented. The couple downstairs owned their flat.
We had a few friends over for drinks for our Birthday. (Mine and DH birthdays are 2 weeks a part so we usually have a joint thing)
CFN lady shows up very upset as our toilet pipe is leaking. (Unbenownst to us at that moment) horrible right? It's leaking in our bedroom (eww) down through the walls and they can hear dripping.
We try to call our landlord. Didn't think we would get very far as it was Saturday night at 2am so agreed we would call them in the morning and avoid flushing the loo untill then.
Not enough for CFN. She waltzes in like she owns the place, goes to our bathroom, takes one of our brand new white towels and wraps it round the leaking toilet pipe. She then announces that she will call dinorod and that she will send the bill to our landlord. Pesters us for ages for his direct number. (We refused to give it out as we knew from prior experience that he doesn't want her having it due to excessive harassing from her over a trivial issue) so we knew he had asked her to email in future if she had any grievances with him.
Let her dog into my flat. One of our guests was allergic. Kept coming and going at her convenience.
She then got her DH involved who decided to turn off our water completely at the mains as they didn't trust us not to flush the loo for 24 hours.
My DH then got involved and ripped him a new one for the water situation.
He had to tell them to stay out of our home. That we would not turn away any plummers they may send over but we can't guarantee our landlord would foot the bill and we would call him first thing in the morning and not flush the loo untill then. She went absolutely mental.
She sent an emergency plummer over (who we obligingly let in at 4am in the morning) Who says that the landlord needs to deal with it as he doesnt have permission to do the work.
A few days pass. They had sorted a temporary fix which had sorted the situation but final works needed to be done to ensure it didnt happen again in a few months time.
CFN downstairs wanted to be kept updated, so we kept them in the loop, they knocked incessantly, multiple times every evening in case they had missed updates. Then one morning at 5am the DH knocked at the door multiple times demanding an update, as they hadn't heard from us in all of 12 hours.
I'd had enough by then. Id tried to be as co operative as possible given the grizzly situation. Basically indicated that he was damn lucky that it was me he had woken up at 5am and not DH (He is NOT a morning person)
That we will be in touch once work had been completed and for him not to knock again or else it WILL be my very angry DH that deals with the situation.
I get that it was a totally horrible situation but the way they dealt with it was insane.
